The OpenSSD Project

The OpenSSD Project is an initiative to promote research and education on the recent SSD (Solid State Drive) technology by providing easy access to OpenSSD platforms on which open source SSD firmware can be developed. Currently, we have offered an OpenSSD platform based on the commercially successful BarefootTM controller from Indilinx Co., Ltd. In addition, we now support an FPGA-based OpenSSD platform whose hardware and software designs are modifiable. This site is also intended to be a forum to share various simulators, tools, and workload generators and traces related to SSDs, among researchers in academia and industry.

OpenSSD Platforms

Another OpenSSD homepage is now open. New announcements, documents, and source codes will be shared on the new webpage which is www.openssd.io. For now, this site would be used for sharing info on Cosmos/Cosmos+/Cosmos Mini. However, it would be used for other projects soon. We cordially invite you to become a project participant, contributor, and user. (The link update may be requested by sending an email to admin@openssd.io or openssd@gmail.com. Thank you!)

The Cosmos+ Platform is yet another PCIe-based SSD platform based on the HYU Tiger4 controller. The HYU Tiger4 controller supports a subset of the NVMe interface protocol. In fact, the platform board is the same as the Cosmos Platform, but with a different storage controller (HYU Tiger4) in FPGA (you can upgrade the board by yourself). However, the Cosmos+ OpenSSD requires new memory modules (w/ toggle NANDs). It is because the recent NAND flash devices we can get support only toggle-mode interface. For further details on the Cosmos+ Platform, please refer to the following material presented at Flash Memory Summit 2016.

The Cosmos Platform is a PCIe-based SSD platform based on the HYU Tiger3 controller. The HYU Tiger3 controller is developed by ENC (Embedded and Network Computing) Lab. led by Prof. Yong Ho Song at Hanyang University, Korea. For further details on the Cosmos Platform, please refer to the following material presented at Flash Memory Summit 2014. The Cosmos platform is available for purchase.
